import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class ScriptEngineManagerTest {
    public static void main(String[] args) {
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByExtension("js");

        try {
            engine
                    .eval("function myFunction(name){var output = '';"
                            + " for (i = 0; i <= name.length; i++) {output = name.charAt(i)+'-'+ output"
                            + " } return output;}");
            Invocable invokeEngine = (Invocable) engine;
            Object o = invokeEngine.invokeFunction("myFunction", "abcde");
            System.out.println(o);

        } catch (NoSuchMethodException e) {
            System.err.println(e);
        } catch (ScriptException e) {
        }

    }
}

其实没感觉到这个有什么用，娱乐一下。
